KAB EV-1 users?

As my Orbitrac starts to come apart from overuse, my thoughts turn to the next logical step. Has anyone used the KAB EV-1?

Seems like about what you would come up with if you were making a DIY RCM, and less complex than, say, Chris Brady's model:

I did a search here and found only one reference. If anyone has used the KAB EV-1, I'd love to hear about your experiences.
